\(यदि (A={x\in \mathbb{N}:x\) is a divisor of \(36}) और (B={1,2,3,4,6,9,12,18,36}) है, तो (n(A)) और (A=B) के बारे में सही विकल्प कौन सा है\)?
\(If (A={x\in \mathbb{N}:x\) is a divisor of \(36}) and (B={1,2,3,4,6,9,12,18,36}), which option is correct about (n(A)) and (A=B)\)?
Explanation opens after your attempt
A. (n(A)=9) और (A=B)(n(A)=9) and (A=B)
Concept
The positive divisors of (36) are (1,2,3,4,6,9,12,18,36).
Why this answer is correct
There are (9) elements, exactly the same as (B).
Exam Tip
Use factor pairs so that no divisor is missed. चरण 1: (36) के धनात्मक भाजक (1,2,3,4,6,9,12,18,36) हैं। चरण 2: कुल (9) अवयव हैं और यही (B) में हैं। चरण 3: भाजक गिनते समय जोड़ी विधि से कोई अवयव न छूटे।
